Community Print 3D Print of 32 Day Clock Easy Build

I almost finished it (version 15 days, picture). - I made all the gears in ABS. They printed perfect, only one of the pieces (gear9_inserts) had to be reprinted due to a small warp. I printed it with enclosure (about 33 ºC) and heated bed (90 ºC). If anyone were to ask me, I would recommend ABS over PLA. I like how I can sand it down to get a really smooth surface. The body, pendulum and hands in PLA. - I understood too late the advice to fix elephant's foot (I use Cura and the parameter for this fix has a name I didn't recognize). So I got some elephant feet. I removed it manually (X-Acto, sandpaper) from the pallet and scape but didn't do any or just a few touches on the other gears. - I didn't use screws (I don't like them) but metal inserts and bolts. In Spain we use metric screws, so I choose M4 screws except for the gear7c_clicks where I used M3. - Gear4b_18 and spacer_4a must have a snug fit to the rod (epoxy and shaft collar are recommended alternatives). Instead, I made a small hole in the wall of these pieces (2 mm drill) and screwed in an M2.5 bolt which perfectly fixed the pieces to the rod. It's a bit difficult to make the hole in the center of the wall of spacer_4a (only 5 mm thick) to keep the bolt head right in the middle (not sticking out on either side of the spacer), so I ended up redesigning the spacer with the screw hole already prepared (picture). - I designed a U-piece that attaches to the wall and supports the bottom of the clock (picture). This piece allows the clock to be vertically aligned by means of two opposite bolts. - I still have to print the weight shell. The current design seems too bulky to me. I found a local business that sells lead bars and I plan to fill a shell with 10x10mm square bars. Lead rods are cheaper than BB's and I expect they will give a higher density. I'll use BB's if needed to fill in the gaps between the body of the square lead rods and the shell walls. I want to thank @StevePeterson for this beautiful, smart and precise design. By the way, you must have a really twisted brain to be able to create something like that using the Imperial system of units.
